A/C question

[c-mack]

hey all, i just had a few questions about getting aftermarket A/C in my 67. ive had it for a while now with no a/c. and didnt really worry about it, but man.....its hot. i live in texas, and just having the vents open, and the windows rolled down just aint cuttin it. i was just wonderin which brand of aftermarket A/C is best/cheapest. ive heard of vintage air, but ive also heard some negative stuff about it from a buddy who put it in his 57 chevy. so....a little input would be great. also if you can get some pics of it that would help out a lot too.

thanks alot all
